Definitions

  • the invention relates to a connecting and / or connecting element for frame parts of upholstered furniture, vehicle seats or the like.
  • a connecting element of this type is known (FR-A-1401 361), in which the two frame wires are pressed apart by a wedge-shaped clamping piece and pressed into the grooves formed by the bent edges of the holder.
  • a toothed surface of the wedge piece rests on one frame wire and a wedge surface of the clamping piece opposite this toothed surface rests on the other frame wire.
  • the object of the invention is therefore to provide a connecting and / or connecting element for frame parts made of spring steel of the type specified in the introduction, which on the one hand can be securely attached to the frame parts without influencing or changing their shape or suspension properties, and in which the frame wires are stuck and lie firmly against the holder along its entire length.
  • the free edges of the flange parts expediently run parallel to the multi-wall sheet and protrude inward beyond the frame wires. Together with the web plate, they then form a guide for the clamping pieces on their front and rear. This ensures that the clamping pieces cannot fall out of the holder to the front.
  • the web plate can be provided with locking devices for the clamping pieces.
  • the web plate can have bumps or serrations on its surface facing the clamping pieces, which prevent the clamping pieces from moving axially after they have been displaced relative to one another and exert the radial pressure on the frame wires.
  • the holder can be provided with connecting parts which can be welded, riveted or screwed onto the holder.
  • the holder itself expediently consists of sheet steel, while the clamping pieces are advantageously made of plastic, which on the one hand has a high strength, but on the other hand also has a certain flexibility and ensures a good form fit between the clamping pieces on the one hand and the frame wires on the other hand in the holder.
  • 10 denotes a connecting element for two frame parts 11 and 12 of a backrest 13 for an upholstered chair, which consists of a C-shaped holder 14 and two clamping pieces 15.
  • the C-shaped holder 14 is made from a piece of sheet steel and consists of a web plate 16 and two flange parts 17 and 18, each of which encloses a frame wire 19 or 20 of the two frame parts 11 and 12 in a tight fit.
  • the clamping pieces 15 consist of plastic, but they can also be made of another material, for example of metal.
  • Each clamping piece has a wedge surface 24 provided with a toothing 23, which has such an inclination that the wedge surfaces are self-locking, i. H. cannot slide back under side load.
  • the wedge surfaces 24 of the clamping pieces 15 face each other.
  • each clamping piece 15 opposite the wedge surface is adapted to the thickness d of the frame wire 19 or 20, wherein in the present exemplary embodiment each clamping piece 15 has a constant thickness b.
  • the clamping pieces 15 On their surfaces 26 facing the frame wires 19 and 20, the clamping pieces 15 have grooves 27 which are adapted to the cross-sectional shape of the frame wires 19 and 20, in the present case they are rounded in a circle.
  • any connecting parts for example a hanging tab 30, to the holder, this is provided with two holes 28 through which rivets or screws, not shown here, can be inserted.
  • locking devices such as projecting knobs or hooks, are arranged on the inner surface 29 of the holder, which dig into the rear surface of the clamping pieces and hold them in place.
  • the backrest 13 of an upholstered chair which, as already mentioned above, consists of two frame parts 11 and 12 made of spring steel wire.
  • the two U-shaped frame parts 11 and 12 are connected to one another by a plurality of connecting and connecting elements 10.
  • the connecting and connecting elements 10 can have different lengths, and that individual connecting parts, such as tabs 31, for hanging in wave springs 32 or a steel beam cross-member are welded or riveted to them.
  • cranked hook-in tabs 30 are welded onto the inner surface 29 of the holder 14.
  • the holder is welded to the inner flanges 17 and 18 in cross section of U-shaped fittings 34, which carry a crossbar 35, which stiffens the frame and ensures a firm contact with the seat of the upholstered furniture.
  • a support 36 can be welded to the two connection elements 10, to which the seat can be screwed later, for which purpose holes 37 are provided in the support.
  • the invention is not restricted to the exemplary embodiment, but a number of changes and additions are possible without leaving the scope of the invention.
  • the holder could also be made of a hard plastic and it is also possible to design the clamping pieces somewhat differently, without leaving the scope of the invention.
